The U.N. special envoy for Syria[1], Staffan de Mistura, has said some participants in the talks would begin to arrive in Geneva on Wednesday, while others would arrive later in the week.
The United Nations says peace talks on the conflict in Syria are to resume within days.
But Riad Hijab, a coordinator for the High Negotiations Committee, which broadly represents the opposition at peace talks, said the Syrian government and its Russian allies were continuing to violate the truce.
The resumption of the dialogue was scheduled for March 7, but de Mistura informed last week about the need to change the start date, in order to ensure the right conditions for negotiations between the sides and a greater scope for compliance with the ceasefire established on February 27. Both sides have accused each other of violations of the cessation of hostilities agreement - the first of its kind towards ending a war that has killed more than 250,000 people and created refugee crises in the Middle East and Europe.
Representatives of the Russian Center for reconciliation in Syria discussed with their US colleagues how the ceasefire agreement is being implemented.
United NationsRussia has already delivered about 620 tons of humanitarian aid as well as medicine to war-torn districts in Syria, Konashenkov said, adding that Russian Federation is also ready to allocate vehicles from its Hmeimim airbase in Syria for the transportation of humanitarian goods.
Hijab also said that "unfortunately" all Russian airstrikes had been targeting moderate rebels. Hijab, speaking in a conference call with reporters, said he had sent a letter to U.N. Secretary General Ban Ki-moon to complain about a map of armed groups' positions, which was published by the Russian Defence Ministry.
Chahine said the peace talks will resume "in a staggered and proximity system", meaning that they will take place in various phases and not face-to-face, at least initially. He also said that they would not accept Assad being permitted to run in future presidential elections.
His statements appeared to be a step back from comments by HNC spokesman Riad Naasan Agha, who said the opposition delegation would arrive on Friday to take part in talks.
"We started to notice that the volume of violations has started to reduce in the last two days".
Asked if the HNC would extend its commitment to the ceasefire, Hijab said the body would discuss the situation on the ground with opposition fighters "and based on this, we will make our decision".
Hijab said a small HNC delegation would travel to Geneva "in the next two days" to meet the worldwide task force monitoring the truce.
